Oscillations of power systems cause instability in power networks. Power system stabilizer (PSS) is used as a conventional method to damp these oscillations . Finding the optimized gain of PSS is one of the major problems in power system stability issue. In this paper, single machine connected to an infinite bus and 10-machines 39-bus network are considered for study. it's shown that finding th...

Metal-semiconductor Janus-like nanoparticles with the composition tantalum silicide-silicon (TaSi₂/Si) were synthesized for the first time by means of an evaporation method utilizing a high-power electron beam. The composition of the synthesized particles were characterized using high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), selective area electron diffracti...

Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. T...

It seems that information is spread over internet and to retrieve useful information easily by mean of intelligent computing is the growing field of research. This need gives birth to semantic web services and various approaches are given for composition of these services. The key problem is to fulfill user’s request. Intelligent Agents are used as a powerful approach for semantic web services ...

althusser (1918-1990) argues that there are two ways to maintain power. in order to hold power, the ruling class in a pre-capitalist society depends on repressive apparatuses such as police and military force whereas in a modern capitalist society it chooses to use ideological apparatuses like religion, education or arts. bamdede khomar is the story of eighty years of development in iranian soc...

in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...
